Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning accessories, in particular to an air-conditioning anti-cross-wind heater shell. Background Art

[0002] Air conditioning, or air conditioner, refers to equipment that uses artificial means to adjust and control parameters such as temperature, humidity, and flow rate of the ambient air in a building or structure. Air conditioning generally includes several major parts such as cold source / heat source equipment, cold and hot medium distribution system, terminal device, and other auxiliary equipment, mainly including: refrigeration host, water pump, fan and piping system. The terminal device is responsible for utilizing the cold and heat distributed to specifically process the air state so that the air parameters of the target environment meet certain requirements.

[0003] For example, China Utility Model Patent Publication No. (CN214564479U) discloses an anti-cross-wind air intake structure for an automobile air conditioner, which includes a shell, and a blower, an external circulation air inlet, an internal circulation air inlet, and an internal and external circulation damper arranged in the shell. An external circulation channel connected to the external circulation air inlet, and an internal circulation channel connected to the internal circulation air inlet are formed in the shell. A filter element is intercepted at the inlet of the blower. A partition member is provided in the shell. The partition member divides the external circulation channel into an external circulation main channel and an external circulation secondary channel. After the external circulation main channel merges with the internal circulation channel, it is connected to the blower through the filter element, and the external circulation secondary channel is directly connected to the blower through the filter element. , and a fresh air damper for controlling the opening and closing of the outer circulation sub-channel is provided on the outer circulation sub-channel, and the inner and outer circulation dampers are located in the closed position of the outer circulation main channel or the inner circulation channel by rotation. This utility solves the problem that during the driving of the car, if the internal circulation + partial external circulation mode is selected, due to the fast speed of the vehicle, the power of the fresh air supplemented by the external circulation is large, resulting in a considerable part of the fresh air directly entering the car through the inner circulation air inlet in the opposite direction, forming cross-wind, which will obviously increase the energy consumption of the vehicle during driving. However, in this patent, the other side cannot be cut off when switching the inner circulation air intake and the outer circulation air intake, resulting in the situation of cross-wind when switching the circulation mode, affecting practicality.

Through the cooperation of the torsion spring, when the air chamber is closed, the support rod drives the closing plate to move, which will stretch the torsion spring. After switching the mode, the support rod opens the closing plate, and the torsion spring applies elastic force to the closing plate to make the closing plate open quickly, thereby improving the switching speed of the cycle mode.

One end of the air inlet pipe 562 is connected to the airbag 561. The other end of the air inlet pipe 562 passes through the partition 4 and is connected to the outer side of the ventilation pipe 53 on the other side. After the ventilation pipe 53 is connected to the air inlet hole on one side, the wind enters the ventilation pipe 53, and a part of the wind is diverted to the air inlet pipe 562. The air inlet pipe 562 passes the wind into the airbag 561 on the closing plate 55 on the other side, so that the airbag 561 Inflation, the reset member 57 includes a rotating shaft 571 and two torsion springs 572.

[0035] The working principle of the above embodiment is:

[0036] (1) When the air conditioner is in the external circulation mode, the left ventilation duct 53 is located at the external circulation air inlet 2. At this time, the left external circulation air chamber is open, the right internal circulation air chamber is closed and the internal circulation air inlet 3 is in a closed state. When the circulation mode of the air conditioner needs to be switched, the electric push rod 511 is turned on, and the output shaft of the electric push rod 511 drives the baffle 52 to move. The movement of the baffle 52 drives the ventilation duct 53 to move, so that the left ventilation duct 53 is moved away from the external circulation air inlet 2. At the same time, the right ventilation duct 53 moves toward the internal circulation air inlet 3, so that the air is switched to the internal circulation mode.

[0037] (2) When switching to the internal circulation mode, the baffle plate 52 moves to drive the first hinge seat 541 to move, and the first hinge seat 541 drives the support rod 542 to move, so that the angle of the support rod 542 on the second hinge seat 543 rotates. As the baffle plate 52 moves to the right, the angle of the right support rod 542 gradually tilts to the right, so that the right closing plate 55 is pushed open, thereby opening the internal circulation air chamber. At the same time, the angle of the left support rod 542 also gradually tilts to the right, so that the left closing plate 55 is closed. After the ventilation pipe 53 is connected to the internal circulation air inlet hole 3, the wind enters the right ventilation pipe 53, and a part of the wind is diverted to the air intake pipe 562. The air intake pipe 562 passes the wind into the air bag 561 on the other side of the closing plate 55, so that the air bag 561 is inflated, so that the sealing of the installation groove 573 and the connecting groove 574 is improved, so as to prevent the wind of the internal circulation from entering the external circulation air chamber and prevent the occurrence of cross-wind.
